Heating and hot water of sports building in renewable energy
Horský, Martin ; Topič, Jan (referee) ; Počinková, Marcela (advisor)
The aim of my work is the heating and hot water for multi-functional building. The first part is devoted to solar systems. And both in terms of use and usability as well as the requirements relating to individual elements of the solar system.Conclusion The first part is devoted to the practical design of solar equipment forhot water. In the second part is devoted to design heating polifunkčního house. There isperformed a complete calculation and design. And the calculation of heat losses to the design of boiler and its connection to the system.

Influence of socio-economic factors on the composition of waste: statistical approach
Jordánová, Petra ; Pavlas, Martin (referee) ; Šomplák, Radovan (advisor)
This bachelor thesis deals with comparison of mixed municipal waste in different areas in the Czech Republic. Statistical apparatus needed for subsequent data is described in the first part. There is discussed problematics of random variable, the probability distribution and hypotheses that will be used in this work. The second part involves a data set analysis. The merit of this thesis is hypothesis testing of the difference in mixed municipal waste composition between chosen areas and built-up area types. At the end an approach for estimate of impact factors of waste composition using correlation and regression analysis will be given. This work brings a benefit in current stratification evaluation process and recommendation of changes in selected factors.

Air-conditioning of Sports Hall
Švub, Oldřich ; Horák,, Petr (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air-conditioning of sports hall. The aim was to design a two to three air-conditioning devices for the sports hall. Introductory theoretical part is devoted to the history of air conditioning, an explanation of the concept of stratification, the description of terminal elements and description of the selected objects, in which the distribution of air is greater than 4 meters. The theoretical part is followed by part of the calculation and design.

Klíčivost semen, metody stanovení a její ovlivnění faktory prostředí
KRAUS, Jindřich
We compared germination rate and germination dynamics of species under different seed stratification treatments (dry, wet, temperature variation). The experiment was performed in laboratory conditions using seeds of ten species from commercial sales. The home site advantage was tested in a field experiment assessing seed germination of three species from four localities differing in moisture and seeds from commercial sales. We analysed the data using generalized linear models.

Numerical assessment of stratification influence in simple algebraic turbulence model
Uhlíř, V. ; Bodnár, Tomáš ; Caggio, Matteo
This paper presents rst few results obtained using a newly developed test code aimed at validation and cross-comparison of turbulence models to be applied in environmental flows. A simple code based on nite di erence discretization is constructed to solve steady flows of incompresible non-homogeneous (variable denstity) fluids. For the rst tests a simple algebraic turbulence model was implemented, containing stability function depending on the stratification via the gradient Richardson number. Numerical tests were performed in order to explore the capabilities of the new code and to get some insight into its behavior under di erent stratification. The two-dimensional simulations were performed using immersed boundary method for the flow over low smooth hill. The resulting flow fields are compared for selected Richarson numbers ranging from stable up to unstable strati cation conditions.

Sport and Czech Society: Sources of Differences in Sports Participation
Špaček, Ondřej ; Numerato, Dino (advisor) ; Sekot, Aleš (referee) ; Leška, Dušan (referee)
The thesis examines changes in sports participation in Czech society in last decades. Sports activities are conceptualized as a practice, routinized habit that is shared in a society's culture (Reckwitz 2002; Warde 2005). Bourdieu's (1984) also shows how different social positions generate different taste and preferences, which are simultaneously classified and base for symbolic borders between social classes. The empirical analysis focuses on sports participation during the last three decades and deeper understanding of differentiation and meanings of today's sports activity. The results clearly show profound increase in sports participation, from 25 % in 1984 to 67 % in 2009. The cohort analysis confirms that dynamics of sports practices' spread have roots in the socialization process and cohort exchange, because younger cohorts have a stable higher level of sports participation irrespective of their aging. Lasting impact of cultural capital on sports participation is particularly striking, especially in the light of the major change in society's regime in the 1989 and after. This brings attention to the question, how mechanisms of social inequalities - especially cultural capital - worked in a similar way across supposedly different social orders. Next chapter deals with patterns of participation in...

Classical concepts of stratification and their comparison with the situation in contemporary society. Subjective and objective position in the social structure
Rádl, Michael ; Šafr, Jiří (advisor) ; Jirkovská, Blanka (referee)
The central theme of the thesis is the current conceptualization of social classes and the issue of stratification in the Czech Republic in the period after 1989. In the first part I confront key theses of classical stratification concepts and follow their transformations in the history of exploration of the social structure. In the second part, by secondary analysis of quantitative data, I am trying to find the key factors of self- classification into social structures and to determine how this subjective self- classification correlates with objective (sociological) classification. An important part of the research is also the question of to what extent and in what sense people perceive the contemporary Czech society as a social-stratified. In the conclusion, on the basis of the results of analysis, I am trying to suggest which of the classical concepts of stratification best reflects the situation in contemporary Czech society. Key words: subjective and objective position, stratification, class, stratum, status, society, social structure

Key factors affecting composition and diversity of saproxylic beetle assemblages
WEISS, Matthias
The thesis concerns the community structure of saproxylic insects with a heavy focus on beetles. It presents a review on change of insect assemblages along small-to-large scale gradients and the importance of saproxylic organisms in forest ecosystems. The fine-scale vertical stratification of saproxylic beetles assemblages and their differences between forests habitats of different latitude and altitude are investigated. Further, the importance of open-grown trees for saproxylic diversity is assessed.

Algebraic inequalities over the real numbers
Raclavský, Marek ; Šťovíček, Jan (advisor) ; Příhoda, Pavel (referee)
This thesis analyses the semialgebraic sets, that is, a finite union of solu- tions to a finite sequence of polynomial inequalities. We introduce a notion of cylindrical algebraic decomposition as a tool for the construction of a semialge- braic stratification and a triangulation of a semialgebraic set. On this basis, we prove several important and well-known results of real algebraic geometry, such as Hardt's semialgebraic triviality or Sard's theorem. Drawing on Morse theory, we finally give a proof of a Thom-Milnor bound for a sum of Betti numbers of a real algebraic set. 1
